IMPBOVEMNT INTAPPET-CHAIN FOR LOOM.

To all whom 'it may concern i `Be it known that I, JAMES NUTTALL, of Walmersly, in the county of Lancaster, in England, have invented a new and' useful Improvement in Looms; and I do hereby declare that the following is a full', clear, vand exactidescription thereof, which will enable y others skilled in the art to make and use the same, ref` erence being had to the accompanying drawings forming part of this specification. i

'This invention relates to improvements in looms,

andconsists `in an improved construction of pattern.

,or tappet chain for actuating the harness-levers or treadles.V l f Figure` 1 represents a front elevation of a pattern- Figure 2 represents a section ofthe same, taken on `the'line xa' of lig. 1. l

Figure 3 represents a plan view `lof one of the tap-` pet-links; and V l Figure 4 represents a similar view of one of' the ordinary links.

Similar 'letters of reference indicate corresponding parts. f

The rods a for supporting and actuating the tappet `links b, are connected at each end by the' ordinary l l vcurved links c, arranged'in the usual manner.

b represents the `tappet .links, which are heartshaped, and provided with two holes', similar to those of the links c for connecting to two rods. These tap-y pets are recessed in their sides, as represented at e, to

The Schedule referred to in thsaLetters'Patent and making part of the same `permitfthem to overlap each other when the figure ofl the goods to be produced requires two or more of the tappets to follow in succession. f

This arrangement permits the chain to be changed to produce various patterns, which changes may be accomplished by slipping both the links c and ,71 o the rods and re-arranging them.

I contemplate using two of these pattern-chains, one on each side of the axis ofthe harness-levers f, under the latter, as represented in fig. 2.

For operating the chains I employ shafts y, tinted throughout their length, the projecting ribs of the said shafts taking into the curves in the base of the tappet-links, similarly to their action with the links c,

whereby the tappet-links are more permanently sup- Witnesses Ran. NUTTALL, GEORGE Hour.
